Yohimbine also helps to increase levels of the coenzyme NAD (or nicotinamide adenine dinucleotide). This affects metabolism, cognitive processes, and detoxification of drugs in the body. NAD is not currently used to treat cognitive or mood-related disorders on its own, but has been shown in some studies to potentially have uses for preventing neurodegenerative diseases including Parkinson’s disease or Alzheimer’s. However on the other hand, studies have found that because it can increase anxiety in some patients, yohimbine may actually worsen mental illness in some patients, including those with Parkinson’s. (15) For this reason, it’s important for anyone taking mood-altering medications, or who has a history of any cognitive or mood disorder, to work with a professional while taking or starting any new herbal treatments.
Magnesium helps regulate levels of calcium, zinc, and other vitamins and minerals. It also helps the body produce energy and contributes to proper organ function. Most people don’t develop a genuine magnesium deficiency, even if they don’t get enough of the mineral in their diets, according to the University of Maryland Medical Center. A true magnesium deficiency, however, may increase the risk of erectile dysfunction.

The sunshine vitamin will brighten things up in the bedroom. In a recent study published in the Journal of Sexual Medicine, Italian researchers found that of 143 men with erectile dysfunction, 80% had less-than-optimal levels of D, and the men with severe ED had, on average, a 24% lower level of D than with a milder condition. They theorize that low levels of D damage blood vessels and lead to a shortage of nitric oxide.


An Italian study in 1994 on 63 patients with psychogenic impotence showed that yohimbine, the active ingredient in the inner bark of the Yohimbe tree, improves libido and sexual stimulation. Half of the patients were given 15mg orally of yohimbine and the antidepressant trazodone 50mg orally per day, the other half a placebo, over an 8-week period. Of the half that received the yohimbine, 71 percent had an increase in sexual desire, erectile function, and ejaculation, as compared with only 22 percent in the placebo group. Patients receiving the placebo then were given the yohimbine tablets over a new 8-week course and of that group, 74 percent showed improvement. After a 3- and 6-month follow-up, positive results were maintained in 58 percent of the patients. To me this is very notable, as the antidepressant trazodone is known to cause sexual dysfunction as a side effect.
Erectile dysfunction supplements and other natural remedies have long been used in Chinese, African and other cultures. But unlike prescription medications for erectile dysfunction, such as sildenafil (Viagra), vardenafil (Levitra, Staxyn), tadalafil (Cialis, Adcirca) and avanafil (Stendra), erectile dysfunction herbs and supplements haven't been well-studied or tested. Some can cause side effects or interact with other medications. And the amount of the active ingredient can vary greatly from product to product.
Data from the Florida Sexual History Questionnaire collected at each time period (baseline, 5.4 mg tid and 10.8 mg tid) are presented in Table 6. Three patients (two responders and one nonresponder) did not complete the entire questionnaire for each study period and were excluded from the analyses. Thus, data in the table and statistical analyses are based on the responses of seven responders and eight nonresponders.

Research is mixed on the effectiveness of acupuncture as an erectile dysfunction cure, but one study published in November 2013 in the Journal of Alternative and Complementary Medicine found that acupuncture can be beneficial for men experiencing erectile dysfunction as a side effect of antidepressants, including selective serotonin reuptake inhibitors (SSRIs) and serotonin noradrenaline reuptake inhibitors (SNRIs).

But in this case, zinc is much harder to absorb. This explains a decrease in testosterone levels in vegetarians. Slippery jack mushrooms, button mushrooms, beef liver, and fish are also rich in zinc. They are followed by breadstuffs, egg yolk, rabbit, chicken, beans, tea, and cocoa. In addition, zinc is found in onions, garlic, and rice. And a very small amount of zinc is available in fruits, vegetables, and milk.

That said, I think that guys like myself who eat a ton of plant foods have to be consider the fact that they may not always be getting all the niacin they could.  Men with lower niacin status can probably give their erectile strength and cardiovascular health a nice boost by consuming more niacin-rich plant foods.  There are many plant foods, such as broccoli and mushrooms that are quite high in niacin.  I actually consume nutritional yeast and BPA-free sardines daily and get a nice amount of niacin this way on top of my regular diet.  Therefore, I feel that I am likely maximizing my erectile strength by combining the best of both worlds, i.e. some NO-boosting plant foods and high niacin foods as well.  (Both  sardines and nutritional yeast also have a decent amount of protein as well, which is important to me since I enjoy lifting weights.)
Studies of mixed organic causes for erectile dysfunction showed varied results;15,16 thus, certain guidelines recommended that it not be used to treat erectile dysfunction.17 Side effects occurred when a high dose was given.18 Patients with organic erectile dysfunction had mixed results, with positive effects in 26,19 33,20 3421 and 43%,22 respectively. The results were better when the dose was doubled.20,21 Several meta-analyses showed a slight positive effect of yohimbine compared with placebo.23,24
When a man becomes sexually excited, muscles in their penis relax. This relaxation allows for increased blood flow through the penile arteries. This blood fills two chambers inside the penis called the corpora cavernosa. As the chambers fill with blood, the penis grows rigid. Erection ends when the muscles contract and the accumulated blood can flow out through the penile veins.

E.D. may just be that early warning sign. Erections depend on blood flow, and blood flow depends on nice, wide-open arteries. Atherosclerosis doesn’t just affect the arteries around your heart; if you have plaque build-up, you are likely to have it all around the arterial system — and the penile artery is one of the smallest arteries you have (no matter what you claim about your size). So if you have atherosclerosis, then the plaque there will be one of the first places where you would notice a decline in blood flow.
"The problem with alternative treatments for any medical problem, including erectile dysfunction, is that until you have about 20 well-controlled studies over several years, you really don't know what you are working with," cautions Richard Harris, MD, a urologist at Gottlieb Memorial Hospital, part of the Loyola University Health System in Chicago.

Good information. However, be sure you are using yohimbine and not yohimbe. Reasons is that I had not realized this difference in the various products I was purchasing and I found out the hard way . Yohimbine can be sold at up to 2% at health food stores legally or you may ask your doctor and it can or is I believe prescribed at 8% yohimbine. I personally love yohimbine for helping me with depression and yes social anxiety. The form yohimbe is much cheaper but the alcoloids can include other stimulate ingredients and the active ingredient the yohimbine is not standardized leaving the user at risk of an uncertain but generally unpleasant overstimulation similar to to much coffee only worse and can last a rather long time up to 10 or more hours. So please just use Yohimbine 2percent and you should be safe . As always consult your medical doctor before taking any new supplements.
When it comes to boosting sexual performance, many men will walk all over God’s green earth looking for ways to maintain a good sex life. Luckily men, all you have to do is walk — not run — 2 miles a day. This, along with other healthier lifestyle interventions can help obese men reduce their risk of ED, or even “reverse” current impotence, according to a 2005 study. This comes of importance, since maintaining a trim waistline is a good defense for ED, as men with a 42-inch waist are 50 percent more likely to have ED than those with a 32-inch waist. Getting to a healthy weight and maintaining it is a good strategy for preventing and treating ED.
Weak erection is one of the most embarrassing problems in this world because i was always shy to meet new partners due to the fact that i already know that i cannot perform at all and even when i did i was so weak. I could only last 45 seconds and this this made me to ask myself many a times if i am a man, four of my girlfriends left me due to this problem. In my search for a cure and a solution i told an old friend all i have been facing and he told me about Dr. MACK how he helped him save his marriage using his very effective ED medicine which restored back his erection. I contacted him and he sent me the medicine and that is one of the best decision i have ever made in my entire life. I think this will help someone out there if you have any ED related problem do not hesitate to contact [email protected] com i know he can help you.

Clinically I have seen these results in doses of just 20 mg twice daily.   It is important to note that prolonged zinc supplementation can lead to lowered copper levels so it is not advisable to continue this therapy unless it is in a cyclical nature.  For those on long term zinc there are combination products with Zinc and Copper.   In cases where some prescriptions that lower zinc are given, like acid lowering meds, thiazide diuretics and ACE inhibitors, or in renal dialysis patients, this chronic monitoring of zinc may lead to longer term supplementation.
When a man becomes sexually excited, muscles in their penis relax. This relaxation allows for increased blood flow through the penile arteries. This blood fills two chambers inside the penis called the corpora cavernosa. As the chambers fill with blood, the penis grows rigid. Erection ends when the muscles contract and the accumulated blood can flow out through the penile veins.
With an inflatable implant, fluid-filled cylinders are placed lengthwise in the penis. Tubing joins these cylinders to a pump placed inside the scrotum (between the testicles). When the pump is engaged, pressure in the cylinders inflate the penis and makes it stiff. Inflatable implants make a normal looking erection and are natural feeling for your partner. Your surgeon may suggest a lubricant for your partner. With the implant, men can control firmness and, sometimes, the size of the erection. Implants allows a couple to be spontaneously intimate. There is generally no change to a man's feeling or orgasm.
One study found that sticking to a Mediterranean diet rich in virgin olive oil, vegetables, fruits, whole grains, nuts, and fish was associated with a lower risk of ED development and improvement in people who already suffered from ED. There is also some evidence that vegetarian and vegan diets may lower the risk of some types of heart disease, which in turn decreases the likelihood of developing ED.
The following parameters were computed using the observed behavioral measures. Copulatory efficiency (proportion of mounts resulting in vaginal penetration relative to the total number of mounts), intromission ratio (number of intromissions/number of intromissions + number of mounts) and intercopulatory intervals (average time between intromissions).[8]
Some men say certain alternative medicines taken by mouth can help them get and maintain an erection. However, not all “natural” medicines or supplements are safe. Combinations of certain prescribed and alternative medicines could cause major health problems. To help ensure coordinated and safe care, discuss your use of alternative medicines, including use of vitamin and mineral supplements, with a health care professional. Also, never order a medicine online without talking with your doctor.
Evidence from 5 randomized studies published in the years between 2004 and 2010, has demonstrated strong evidence that aerobic exercise can benefit people with arterogenic ED. These review results of this study build on and update the evidence from studies that concluded that concluded that exercise was beneficial for people with ED and cardiovascular disorders (25–27); on ED and obesity (18) and on normal subjects with ED (24). However, studies have shown common pathway for ED, cardiovascular (28 –30) and metabolic disorders (19, 31).
Yohimbe supplements haven't been tested for safety and keep in mind that the safety of supplements in pregnant women, nursing mothers, children, and those with medical conditions or who are taking medications has not been established. You can get tips on using supplements here, but if you're considering the use of Yohimbe, it is essential that you talk with your physician first. 
When stimulated by the nerves, the spongy tissue arranges itself in such a way that more blood can be stored in the penis. The veins running through the outer sheath of the penis then compress which stops the blood from leaving the penis. As the blood is stopped from flowing out, the penis fills with blood and stretches within the outer casing, giving an erection.

There are two things that need to be looked at in recommending a supplement for a medical condition: what is the physiology of the medical condition and what is the pharmacology of the supplement you are using.  There then is a search for a link between the two that leads to a tie in with a therapeutic approach.  In some ways this is like a logic course that says A causes B, B causes C therefor A causes C.  We then must apply this to the scientific method and finally the ultimate test: clinical response and safety.  This is often made out to be the gold standard for our typical Rx meds that I dispense every day, but often ridiculed when it crosses the barbed wired “nutraceutical” boarder.  If it is a nutrient then we must be getting the right amount in our food after all right?  Regardless of 1)what the real amount is in the food we eat, not to mention 2)the depletion that may be taking place of that nutrient due to a prescription drug we are taking (an absolute science based cause and effect) – we blindly accept what our food has in it and the level our bodies maintain – this is an incorrect assumption.  In fact it is quite ironic that the anti-nutraceutical court is still hanging onto this assumption when both are established by science.


It’s hard to concentrate on what’s happening in the bedroom when you’re thinking about problems at work. For many men, it’s psychological issues like anxiety rather than physical ones that contribute to E.D. Chronic stress has also been linked to heart disease, high blood pressure, depression, and more. Find a way of blowing off steam that works for you (I like exercise and meditation) and stick to it.
Suggested intake: “The problem with yohimbine is that you can’t regulate the amount in a dosage,” says Fratellone. “It all depends on what part of the tree it comes from, how it’s cultivated, how it’s exported, and so on. The amount of extract you get will vary.” FDA researchers analyzed a number of over-the-counter yohimbe bark products. They found that the supplements contained only seven percent or less of the amount of yohimbine that would be found in actual yohimbe bark, which suggests that they contained little or no yohimbe. However, the prescription form of yohimbine is strictly regulated by the FDA. It is approved only for the treatment of impotence, and is available in tablets and capsules. For erectile dysfunction, 5.4 to 10 milligrams three times daily has been studied and regarded as generally safe.
Though higher doses of zinc reduce libido, supplementation with a medium dose (5 mg/day) has some beneficial effect on the sexual competence of adult male rats. The major significant effects of this dose of zinc are prolongation of ejaculatory latency without disturbing sexual arousability, motivation, penile erection and sex vigor. Also, the partner preference index of the 5 mg/day group was positive and comparable to the controls. A positive partner preference index is indicative of unchanged sexual interest of males.[16] These results confirmed that libido and sexual interest are not affected by zinc supplementation with a 5 mg/day dose. However, mild reduction in percentage of intromission was observed in this group and it is postulated that this may be situational rather than an effect of supplemented zinc. This is based on our observation where mild rejection by the females at the initial phase of the behavior led some males to refrain from sexual activity.
Controlling stress, having a healthy diet, and getting enough sleep to create a good foundation for sexual satisfaction. But sometimes the basics aren’t quite enough. Millions of men experience erectile dysfunction (ED), but ED can usually be successfully treated with prescription medications like Viagra, Levitra, Staxyn, and Cialis. These drugs have helped men understand that ED isn’t all in their mind, have opened up the topic to a more honest discussion, and have transformed many men’s sex lives.
Although you should steer clear of supplements advertised online, research shows certain vitamins and herbs can help ED. They may help improve the health of your blood vessels, increase blood flow to the penis, and boost erectile function. If other treatments have failed, you’re not a candidate for ED medications, or you’re looking for a more natural approach, ask your doctor whether these supplements could be right for you. Here are three to discuss with your doctor:
This is one B team you want to get on pronto: A recent report from Harvard University highlighted a study that has linked low levels of B12 to erectile dysfunction. A causal link hasn’t been nailed down, but the B vitamin is used by every system in the body, particularly in cell metabolism and the production of blood — two essential factors in getting and keeping a quality erection.

Males consuming yohimbine HCL for its pro-erectile benefits should take 5.4mg to 6mg three times per day but don't expect for the results to be noticeable until after about two to weeks of consistent dosing. [4] Not all males will experience this benefit so if you do not notice a change after four weeks of consistent dosing then consider stopping supplementation altogether.
Depending on dosage, yohimbine can either increase or decrease blood pressure Small doses can increase blood pressure. Higher doses can lead to a potentially dangerous drop in blood pressure. Higher doses of oral yohimbine may have numerous side effects, such as rapid heart rate, overstimulation, unusual blood pressure, cold sweating, and insomnia.
When given orally, yohimbine reaches peak levels in 10–15 min, and the half-life is 0.6 h. The efficacy of yohimbine in sexual function has been questioned, perhaps because of early questionable multidrug preparations.10,11 Yohimbine has been shown to have some effect on psychologic erectile dysfunction12,13 and in reversing fluoxetine-induced sexual dysfunction.14

Along with promoting overall health, a sufficient daily magnesium intake can help significantly if you take zinc to promote healthy erectile function or to help alleviate ED. Zinc is often recommended as a natural ED remedy, particularly for men who have a zinc deficiency, according to MayoClinic.com. Magnesium helps regulate zinc levels in the body to support healthy erectile function. Herbs, vitamins and minerals, including magnesium, haven’t been widely studied in terms of their true benefits for men with ED or other erectile problems, but maintaining adequate levels of essential vitamins and minerals may help a doctor narrow down the cause of such problems.
There have been some studies to suggest that a placebo effect that improves ED may work for some men. One study found that men taking an oral placebo pill showed as much improvement in ED symptoms as men who took actual medication to improve ED. Conversely, men who were given therapeutic suggestions to improve ED did not see signs of symptom improvement.
Yohimbe can interact with several drugs and medications, so it’s not safe for everybody to use. Don’t take yohimbe bark if you’re currently taking any ACE inhibitor drug, beta blocker, SSRI drug, MAOI, stimulants or caffeine-containing drugs, or tricyclic antidepressant drugs. Those who have any of the conditions listed below should not take herbal treatments like yohimbe without speaking with a doctor first. This is because it may affect things like blood pressure, heart health, kidney function and neurotransmitter functions:
However, the case is entirely different for Niacin, as it is not only relatively more convenient, but also it allows men to enjoy sex any time when they want even when they take Niacin for only one time in a day for erectile dysfunction. Niacin formulates in the form of various slow-release pills designed primarily to seep in a slow way within the human bloodstream during the course of one day.
A physical exam checks your total health. Examination focusing on your genitals (penis and testicles) is often done to check for ED. Based on your age and risk factors, the exam may also focus on your heart and blood system: heart, peripheral pulses and blood pressure. Based on your age and family history your doctor may do a rectal exam to check the prostate. These tests are not painful. Most patients do not need a lot of testing before starting treatment.
Where it comes from: Yohimbe is derived from the bark of a west African evergreen tree. Yohimbine is an active chemical (an alkaloid) found in said bark and is cultivated into supplement form. Yohimbine hydrochloride is a standardized form of yohimbine that is available as a prescription drug in the United States. These terms are all related but are interchangeable.
The key to all of this is the endothelium, the inner lining of blood vessels that helps blood flow smoothly. Regular exercise has been shown to improve the way the endothelium works. The endothelium lines the blood vessels in the heart and the penis, explains Dr. Hellstrom, but the blood vessels in the penis are about one-third the size of those in the heart. So if you fail to have erections due to vascular problems, that indicates that you’re at risk for heart problems as well.
Test was terminated after 15 minutes of observation or after ejaculation (whichever occurred first). Ejaculatory latencies were taken as 15 minutes when animals showed intromissions but failed to ejaculate during the test period. After analyzing the results, the following tests were performed with the group that indicated significantly positive effects compared to the controls:

Ancient Incans consumed this energizing Peruvian plant before battle or a bout of sex, Chris Kilham, an ethnobotanist at the University of Massachusetts at Amherst, told Outside Online. Maca increases sexual appetite, stamina, endurance, and fertility. One 2008 study conducted at the Depression Clinical and Research Program at Massachusetts General Hospital in Boston found that maca helped people with antidepressant-induced sexual dysfunction to regain their libidos.

In the end, open and honest communication with your therapist will yield the best course of action. If you do decide to try pelvic floor PT, a comprehensive evaluation will determine what exactly is going on with your muscles. They may be tight and weak or they could have poor coordination. So my advice for those suffering from erectile dysfunction is this: before you try kegels, make an appointment with your pelvic floor therapist.

Because the study included only subjects with dyslipidemia, the results may not be applicable to those with ED who have a normal serum lipid profile. Furthermore, patients using aspirin or NSAIDs were excluded to avoid the effect of these drugs in inhibiting prostaglandin D production, which may be one of the potential mechanisms for the effects of niacin on ED. It should be noted that it is quite common for ED patients to have coexisting cardiovascular disease that requires the use of aspirin. Therefore, further study on the interaction of aspirin and niacin in ED patients may be needed to establish the role of niacin in clinical usage.

Does drinking water improve erectile dysfunction? Erectile dysfunction or ED is a common concern for men. Everyday factors, such as hydration levels, may affect a person's ability to get or maintain an erection. Drinking water may, therefore, help some men with ED. In this article, learn about the link between hydration and ED, and other factors that can cause ED. Read now

What it’ll do for you: “Yohimbe dilates the blood vessels and can lower blood pressure,” says Dr. Patrick M. Fratellone, an integrated physician with a practice in Manhattan. “So experts figured, if it can do that, it must give you an erection and treat erectile dysfunction.” Some proponents say that yohimbe extracts are powerful antioxidants that can prevent heart attacks, act as a stimulant and an anti-depressant, and an aid to weight loss. Here, a closer look at the key benefits:
These medications don’t work for everyone but they are easy to use and work for around 60% of people who try them. They work by making it easier to get an erection by reducing the effect of (inhibiting) the chemical PDE-5. This chemical is used in the body to make sure there isn’t too much blood in the penis during an erection, but if you have erectile dysfunction then this chemical ends up over-compensating.

In a recent study, moderate-intensity exercise such as walking briskly and light cycling was shown to boost mood for up to 12 hours. Exercising every day might be best to lift your mood, but strive for at least 5 days a week. Another study showed exercise can improve your body image, regardless of body weight or shape. And feeling good about your body is a great start toward making the bedroom a happier place.
A vacuum erection device is a plastic tube that slips over the penis, making a seal with the skin of the body. A pump at the other end of the tube makes a low-pressure vacuum around the erectile tissue, which results in an erection. An elastic ring is then slipped onto the base of the penis. This holds the blood in the penis (and keeps it hard) for up to 30 minutes. With proper training, 75 out of 100 men can get a working erection using a vacuum erection device.

Three subsets (eight in each subset) of sexually experienced adult male rats were supplemented with three different oral doses of zinc sulphate (a daily dose of 1 mg, 5 mg and 10 mg respectively) for two weeks. A subset of eight animals without zinc supplementation was used as the control group Sexual behavior was observed by placing them individually in cages with receptive females.


As mentioned above, the extract of yohimbe bark has been used as an aphrodisiac for centuries. Recently, yohimbe supplement also became popular for its bodybuilding and fat-burning properties, despite the lack of data to support it as a dieting agent. In addition, supplement manufacturers claim that yohimbe can be used for the following applications:6,7

Testosterone levels did not differ statistically in the treatment groups and did not change during treatment with yohimbine. The levels of dehydroepiandrosterone and free testosterone tended to be higher in the responder group, but the levels in both groups were well into the age-adjusted normal ranges. Androgens play a part in peripheral erectile activity, but they are not necessary for the central arousal stimulation of yohimbine,36 in which norepinephrine release acts as an inhibitor antagonist.2 Peripheral sympathetic stimulation also occurs37 but less than its adrenergic antagonistic activity. These peripheral effects are prompting the search for new alpha-2 adrenergic antagonists38

The lack of strong scientific proof that vitamin supplementation can improve erectile function doesn’t stop companies from selling vitamins, herbal supplements, and other products with the promise that they will do the job. ED is often treatable with prescription medications or medical procedures, so be careful not to get taken by a manufacturer’s empty promises.


Low levels of zinc can be the cause for a variety of health-related problems. Zinc is a key mineral that cells use to metabolize nutrients. Immune function, DNA and protein production, and cell division are all related to zinc levels in the body. Zinc also enables the male body to produce testosterone. Because of this, your levels of zinc may affect erectile dysfunction.
